Designed by the same engineering team behind all of casper sleep products, the dog mattress is a universally comfortable sleep surface for our four-legged friends. We combined our mattress-making know-how with extensive dog-centered research to create a sleep environment that caters to canines natural behaviors. Pups spend more than half their lives sleeping. Even the most well-behaved dogs have bad days. But no matter how rough they play, most dogs can’t rip through our durable cover material it’s made with one of the strongest bonded microfibers available. It’s so tough, similar materials are used in performance footwear designed to withstand years of abuse. This bed will keep its shape, thanks to its fortified construction it won’t sink, slump, or sag over time. Dogs scratch or dig before laying down. That’s an instinct they inherited from their wild ancestors, who would kick up dirt to find cooler ground and brush away debris before turning in for the night. So dig in doggies. There’s a reason pups like to squeeze into tight spaces. They’ve learned to seek refuge from predators, so they feel safest in enclosed areas.
